The Microsoft Visual Studio workspace (DSW) is a legacy configuration file format developed by Microsoft for managing development project structures. It was primarily used in Visual C++ 6.0 to organize multiple related projects and coordinate build dependencies within a single environment. While this text-based format is generally considered safe, it has been superseded by the modern Visual Studio Solution (.sln) format and is now functionally obsolete in contemporary software development.
